How to Color Fill your Laser Engravings?

The process varies depending on the material you're working with. Here's a closer look at two common materials. Watch this video on how to color fill your laser engravings using Monport GI30 color laser engraver.

  • Non-Metallic Materials (Plastics, Wood, Acrylic, Leather):

    • Limited Natural Color Change: Unlike metals, these materials don't exhibit inherent color variations during laser engraving.
    • Coloring Techniques:
      • Pre-Colored Materials: Embrace the inherent colors within the material itself. Opt for acrylic sheets available in a vast spectrum of vibrant hues, or utilize wood pre-treated with dyes or stains. The laser engraving process will reveal the contrasting color hidden beneath the surface, creating a stunning two-toned effect.
      • Paint Application: This method offers extensive creative freedom. Apply paint directly to the engraved areas using various techniques:
        • Brushing: For broader coverage and detailed work.
        • Wiping: Achieve a subtle, antique-like finish.
        • Stencils: Create intricate designs and lettering with crisp lines.
  • Metals:

    • Natural Oxidation: High-powered lasers can induce a chemical reaction on certain metals like stainless steel and titanium. This process, called oxidation, creates a thin layer of oxide on the metal surface, resulting in vibrant colors like gold, blue, and black.
    • Grating Method: For metals that don't exhibit natural color variations during oxidation, a colored oxide layer can be applied beforehand. The laser beam then interacts with this pre-applied layer, selectively removing portions to reveal the desired color underneath.

Choosing the Right Materials and Color Laser Engraver

  • Monport Desktop 40w CO2 Laser: This color laser engraver is specifically designed for non-metallic materials like:
    • Plastics (e.g., acrylic, polyethylene)
    • Wood
    • Acrylic
    • Leather
  • Monport MOPA GI Series: Designed specifically for metals, this laser offers precise engraving and the ability to leverage the natural oxidation process for color creation on compatible metals.

Remember: When using the Monport 40W CO2 Laser engraver for color filling, primarily rely on pre-colored materials or paint application techniques. The Monport GI30 MOPA excels at utilizing the natural oxidation process and grating method for color creation on compatible metals.

Color Filling Techniques

Here's a step-by-step guide how to color fill your laser engravings:

  1. Prepare your engraved piece: Ensure the engraved surface is clean and free of dust or debris. You can use a microfiber cloth or compressed air for cleaning.

  2. Choose your paint: Select a paint suitable for the material you're working with. Acrylic paints are a popular choice for both wood and non-metallic materials. Opt for high-quality paints that adhere well to the engraved surface.

  3. Apply the paint: There are several methods for paint application:

    • Brushing: For broader coverage and detailed work, use a fine-tipped brush. Apply a thin layer of paint, focusing on filling the engraved areas.
    • Wiping: For a subtle, antique-like finish, apply a thin layer of paint and then gently wipe away the excess with a soft cloth, leaving color primarily within the engravings.
    • Stencils: Create crisp lines and intricate designs with stencils. Secure the stencil onto the engraved surface and apply paint using a brush or a small sponge.
  4. Multiple coats (optional): Depending on the desired color vibrancy, you may need to apply additional coats of paint. Allow each layer to dry completely before applying the next.

  5. Cleaning and finishing: Once the paint is dry, carefully remove any excess paint around the engraved area using a cotton swab dipped in rubbing alcohol (for non-metallic materials) or a suitable solvent (check compatibility for metals).

Additional Tips:

  • Software plays a crucial role: Utilize Lightburn software, compatible with both Monport machines, to design your artwork and control the laser precisely. Lightburn offers features like image editing, layer control, and power settings to optimize your color filling process.
  • Experimentation is key: Practice on scrap materials to test different color combinations, paint application techniques, and laser settings before working on your final project.
  • Safety First: Always wear proper eye protection when operating the laser and ensure adequate ventilation in your workspace.

By understanding the potential of Monport's laser technology, color filling techniques, and safety measures, you can unlock a world of creative possibilities. From personalized gifts and eye-catching signage to artistic masterpieces, color filling adds a new dimension to your laser engraving projects.
